One World Lithium Announces That They Have Received Natural Brine Samples for Testing Using Direct Lithium Carbonation Extraction Technology and Closing Term Loan Financing

(TheNewswire)

VANCOUVER, BC – July 16, 2025– TheNewswire - One World Lithium Inc. (CSE-OWLI) (OTCQB- OWRDF) (the “Company” or “OWL”) ispleased to announce it has now received two separate lithium brinesamples from a major mining company’s lithium project in SouthAmerica. The samples are currently at the lab where they will betested for Lithium Recovery using the Company’s novel lithiumrecovery technology that will enable lithium carbonate productiondirectly from natural brines in a single step.

In November 2024, OWL acquired two patent applicationsthat permit it to commercialize the recovery of lithium using a DirectLithium Carbonation Extraction Technology (“DLCE”) fromspecified sources including natural brine and slurries made frompegmatite, clay volcanic rock and sediment . TheCompany will be funding the development, testing and R&D work associated with these patentapplications.

Primary Project Goals -Ongoing Testing at Lab

The aim of the lab work being conducted now is to continue to validateand expand  the technology to extract lithium carbonate from brine.This project also plans to explore the production or coproduction of additional elements such assodium, calcium, and magnesium from the brine.

This process does not require pre-concentration, baseconcentration, or post-concentration steps as used in evaporationponds and direct lithium extraction processes. With no sorbents, noacids, and no soda ash, a cleaner lithium extraction can be achievedwith substantially lower capital and operating costs.

Funding for the Test Work

The Company has entered into an Umbrella TechnologyAgreement (the “ Agreement ”) with the major mining company toassist in the funding of this stage of testing on the two (2) separatebrine samples. During the testing period, themining company will have the right to continue to work with OWL toadvance the technology by contributing to the financing of a phase twoprogram to continue the R&D work on the technology.

The Phase two program will include expanding labfacilities, purchasing additional equipment and the hiring ofadditional lab workers which will all lead to the construction of aninitial containerized pilot plant for the further testing of lithiumrecovery from natural brine and slurries.

Closing of a Term LoanFinancing

The Company also announces a first tranche closingpursuant to its previous news release of April 4, 2025. The Company has entered into Loan Agreements (the “Loans”) with lendersborrowing a total of $107,200. The Loans areunsecured and will bear interest of 8% per annum. The term of the Loans will be twelve (12) months or five (5)business days following a written notice of the Company that theCompany has raised a minimum of one million dollars through an equityor debt financing.

As an inducement for the Loans, the Company has issuedan aggregate of 3,573,332 share purchase warrants to the lenders. Eachshare purchase warrant will entitle the holder to purchase one commonshare of the Company at an exercise price of C$0.05 for a period oftwenty-four (24) months expiring on July 15, 2027. All securitiesissued under the Loan will be subject to four (4) months and one dayhold period expiring November 16, 2025.

The net proceeds from the Loans will be used to furtherthe research and development of the lithium extraction processdescribed above, and for working capital.

Doug Fulcher, President, CEOstates: “ This is a huge step forward for the Company, securing thenecessary funds to carry out this test work and to having additionalnatural brine and clay samples to extract lithium from which willfurther validate the DLCE Technology.”

Forward lookinginformation is based on certain key expectations and assumptions madeby the management of the OWL, including, but not limited to: (I) theability of the OWL to further develop its DLCE Technology tochange the lithium extraction industry, and (II) OWL’s ability to commercialize its lithiumextraction technologies. Although OWLbelieves that the expectations and assumptions on which such forwardlooking information is based are reasonable, undue reliance should notbe placed on the forward-looking information because OWL can give noassurance that they will prove to be correct. There can be no assurance that such statements will prove to be accurate and actual results and future events could differ materially from the those anticipated in such statements, important factors that could cause actual results to differ materially from the company’s expectations include: (I) the inability of OWL to commercialize itsDLCE Technology (II) OWL’s inability to execute its business planand raise any required financing, (III) risks and market fluctuations common to the mining industry and lithium sector in particular, and (IV) advancements in other new direct lithiumextraction technologies. The reader is cautioned that assumptions usedin the preparation of any forward-looking information may prove to be incorrect. Events or circumstances may cause actual results todiffer materially from those predicted, as a result of numerous knownand unknown risks, uncertainties, and other factors, some of which arebeyond the control of the OWL.
